The hour-long special begins with the exploration of Nebraska’s fresh water resources. Near Roscoe, Nebraska a portion of the geologic formation that makes up the Ogallala Aquifer lies exposed at the surface and we learn how the water below the ground is connected to the water flowing in our rivers. We trek to the headwaters of the North Platte River high in the Colorado Rockies then follow the flow of this historic river through three states to discover how it helped settle the west. And in the Sand Hills, we shadow three researchers as they continue to gather more information about how an ancient mega-drought turned the vast grass covered dunefield into a barren desert.
